I have some programs that run FTP scripts to drop off and pick up some files to/from a LINUX server.  Suddenly, they (vendor who hosts server) have said they're shutting off FTP and want me to use SFTP (port 22) instead.  In my scripts, I don't even specify a port (only an IP address), but I guess it's defaulting to port 21 (?).  Anyway, here are a couple examples of simple FTP scripts currently running happily (they are run by CL and RPG programs).  What do I need to do in order to have them use SFTP instead?  I don't suppose it's as easy as adding :22 to the end of the IP address...?

This one gets a list of files to pick up:

OPEN 'xx.xxx.xxx.xx'
USER myftpuser myftppwd
ASCII
Namefmt 1
SENDEPSV 0
LS (Disk
CLOSE
QUIT

This one picks up a file:

OPEN 'xx.xxx.xxx.xx'
USER myftpuser myftppwd
ASCII
Namefmt 1
SENDEPSV 0
lcd /ecommerce/inbound
GET myfile.csv
RENAME myfile.csv myfile.old
CLOSE
QUIT

This one drops off a file:

OPEN 'xx.xxx.xxx.xx'
USER myftpuser myftppwd
Namefmt 1
SENDEPSV 0
lcd /ecommerce/outbound
MPUT shipments*.csv
CLOSE
QUIT

They just notified me today and want to make the change today... yikes.

Thanks.
